Security_review: Invalid argument supplied for foreach()

Ever since I installed version 6.x-1.1 of the security_review module, I get the following error:

Invalid argument supplied for foreach() in /my_site/public_html/modules/security_review/security_review.checks.inc on line 378.

The failed logins page doesn't display the URLs.
page: /admin/reports/security-review/help/security_review/failed_logins

Code lines 378-381 are:
foreach ($results['value'] as $ip) {
$element['findings']['items'][] = array(
'safe' => check_plain($ip),
'raw' => $ip,

In addition, there is a blank line that displays between the lines: Dangerous tags were not found in any comments. and Error reporting set to log only.
After running security review, it does display a green check.

Any help would be appreciated.

(Someone in the modules forum suggested I post this here...could be a bug?)

Thanks much,
Denise
